SECTIONAL WHEEL-TIRE.'

To ,qll whom 'it may concern:

Be it known that I, J oHNC. LiGI-iTHoUsr., a citizen of the United States, and resident of Rochester', in the county of Monroe and State of New York, have inventedcertain new and useful Improvements -in Sectional WheelTires, of which the following 4is va specification.l This invention relates to sectional wheel tires, and consists in the apparatus hereinafter described and claimed. The object, of the invention is to provide a. wheel tire having a tread portion consisting of compressible material, such as india rubber, lea-therl or wood, divided into tread blocks, which tread blocks are held in block holders fastened on the telly of the wheel, and' having provision for remo-val ot' the individual tread blocks for repair or replacement.

-In the drawings F igure l is a side elevation of a wheel embodying this invention, parts being broken away to exhibit interior construction; Fig. 2 is an end elevation of the same wheel, in which parts' lare also broken away to show the arrangement; Fig. 3 is an enlarged section through the center ot a tire block, its holder and the contiguous part-s upon a wheel; Fig. 4 is a vertical section on the line 4 4 of Fig. 3; Fig. 5 is a perspective view of one of the "end plates of a tire block holder; Fig. is a perspective viewot one of. the bottom plates ot' a tread block holder;v and Fig. 7 is a perspective. view of one of the plates set in a tread block.

In the drawings the invention illustrated as applied to a wheel having a hub l, a series ot spokes and ar telly 3. `On each side ot the telly is a side plate 4, and the two side plates are held on the'telly by bolt-s 5, passing through both side plates and the telly. The side plates are made/of such form as to hold therein a series of tire sections under some'pressure, so as to prevent lateral movement thereof on the felly, and for this purpose each side plate has on its inner surface a circumferential groove 6 and a circumferential rib :fr projection 7. When the side plates are in position on the wheel, as shown particularly in Fig. 8, they torni a groove or cl'iannel'for the tire sec- `tions, and the tire sections are so formed as to bottom in said groove, in order that the road pressure may be transmitted directly to the hub and axle of the wheel.

` Inthe circumferential groove betweenI the side plates are fitted a series of tread block holders, each consist-ing ot' a bot-tom. plate ,8, having end flanges 9 turned up therefrom. Outside of the flanges 9 are end portions l0, having preferably contours registering with Specification of Letters Patent. Patented Sept. 13, 1910. Application filed November 18, 190B. Serial No. 1163,29?.

those ot' the flanges 9, and having inwardly t turned edges ll't'or afpurpose to be described.

The contours of the flanges 9 and of the end plates l0 are such as tobottoin in the groove above mentioned between the side plates 4, and to tit by a projection l2 and a notch or depression ,i3 the corresponding grom'e (3 and rib or projection T in each of the side plates, so that. when the side plates are firmly clamped onthe telly by' the bolts 5, the holders will be tiiirnly locked in place. Through the side plates 10 and flanges 9 are pertorations 14, whereby the holders may be pivoted upon a ring setvconcentric to the telly 3. rThis ring is capable of being` loosened and tightened in any suitable. way, as by a right-and-lefthand nut lll tit-ting on correspending` threads on the ends of the ring. Upon turning the nut, the ring` may be so contracted and tightened that all the l tread-block holders are firmly clamped in the bot-tom pt' the groove between the-side plates.

Tread blocks 17 are provided,A in each of v,which is embedded a plate 18 having its edges flush with the end surfaces of the block, so that the inwardly turned edges or hooks 1l ofthe end-plates l() may engage the outer surface of 'the plate 18, and when the t-ire sections are locked in position by the ring l5 and the side plates, the hooks ll draw the plate- 18 toward the center ot the wheel, and thus clamp the tread block lirmly between the end plate l0 and against the bottom plate S. The opposite ends of the tread block 17 are provided with' transverse tongues 19 and grooves' 20, so that when all the parts are in place the tongues and grooves of the adjacent tread blocks will intermesh and tend to loclr all the parts together, and to prevent passage of dirt, sand,

&c., toward the interior of the apparatus.

It will be noted that the inwardly turned edges or hooks 11 are arranged transversely to the circumference oi. the wheehland it will be clear that upony removal of one of the side plates 4, and the loosening of the ring 15,

any tread block 17 may be slid out from under the hooks vl1, and be replaced by v another, if de ired, or the same block may 'or projections, in or er to `present a greater. and. more 1rregular grlpping suriaeethereto. j

be inserted again. The lines of the tongues and grooves 19 and 2G are arallel to the line of movement necessary or the removal of which the tread blocks areV formed shall y be compressed, and thus produce a better resisting tire. The `faces yof the blocks that strike the ground ma be provided with lugs Said projections in the present instance are `shown as ribs 17 that extend at an angle to the ircumference 'of the wheel and to each i ripherally therefrom and ripheral groove andv removable on one side ;`v
